“…Patellar luxation has an important place among hind leg lameness in dogs (Canis lupus familiaris). It is possible to encounter both large and small breed dogs [1,2,3,4,5,6,7]. The luxation may be medial or lateral.…”

“…The diagnosis of patellar luxation is easy with clinical examination as well as radiological examination [6,15,16,17,18]. Among the surgical treatment methods, besides soft tissue techniques, bone correction operations such as block recession sulcoplasty, wedge recession sulcoplasty, and tibial tuberosity transposition have also been defined [5,6,19]. Various complications can be encountered in many of these operative techniques.…”

Patellar luxation is one of the important orthopedic problem in dogs. Patellar luxation, which has been accepted as a developmental disorder in recent years, usually occurs medially in small breeds and laterally in large breeds. The aim of this study was to evaluate surgical treatment (femoral trochleoplasty, tibial tuberosity transpositions and imbrication techniques together), postoperative complications, early and late results in dogs with patellar luxation. Thirty–two dogs with grade 3 and grade 4 patella luxation were used in this study. While patellar luxation was treated in all cases, tibia fracture was seen in one dog as the most important complication. During tibial tuberosity transpositions technique, attention should be paid to the cutting process and the tibia should not be weakened. In conclusion, the combined use of femoral trochleoplasty, tibial tuberosity transposition and imbrication techniques can be used for patellar luxation. Complete recovery may not be possible in grade 4 patellar luxations.

A non-reducible tibial tuberosity fracture is a rare complication of tibial tuberosity transposition performed during correcting of medial patella luxation (MPL) in dogs. This condition severely disrupts the quadriceps extensor mechanism, leading to significant pelvic limb lameness. An 11-year-old, 1.8 kg spayed female Yorkshire Terrier sustained a comminuted left tibial tuberosity fracture during surgical correction of an MPL. Six months after surgery, the dog was markedly lame and unable to extend the left stifle. Radiographs revealed patella alta and resorption of the fragmented tibial tuberosity. A composite frozen allogeneic calcaneal tendon–bone block was utilized to reconstruct the tibial tuberosity and reattach the patellar ligament. Initial postoperative radiographs confirmed restoration of a normal patellar ligament to patella length ratio (1.42). Both the allogeneic bone used for tibial tuberosity reconstruction and the tendon used to reattach the patellar ligament were successfully integrated. The dog regained satisfactory limb function without recurrence of patella luxation, as reported by the owners 29 months postoperatively. The use of a calcaneal tendon–bone allograft effectively restored the functional integrity of the quadriceps extensor mechanism, providing a viable option for addressing quadriceps insufficiency resulting from the loss of the osseous tibial insertion.
